[0018] Hereinafter, an embodiment of a support device according to the present invention will be described in detail with reference to the drawings. In the following description, when directions such as up, down, left, and right are indicated, they refer to up, down, left, and right when viewed from the front of the figure.

[0019] <Outline of the support device> As shown in Fig. 1, the support device 1 according to this embodiment is installed in front of a blackboard 10 (an example of a display board) installed on a wall surface 12, and while supporting a display device 11, it slides and moves in the left-right direction in the figure along a first guide rail 15 and a second guide rail 16. This support device 1 is mainly composed of a main body section 2, a first sliding section 5, a second sliding section 6, wheels 7, and a pulley 8. Below, the first guide rail 15 and the second guide rail 16 will be explained first, and then each component of the support device 1 will be explained in detail.

[0020] <Explanation of the first guide rail> First, we will explain the first guide rail 15. As shown in Figures 1 and 2, the first guide rail 15 is a member that extends in the left-right direction shown in Figure 1 so as to follow the upper end of the blackboard 10, is fixed to the wall surface 12, and has the first sliding part 5 attached thereto.

[0021] As shown in FIGS. 3 and 4, the first guide rail 15 is composed of a fixed member 15a that is fixed to the wall surface 12, and a rail member 15b that is engaged and fixed to the fixed member 15a.

[0022] As shown in FIG. 3, the fixing member 15a is a member with a convex shape in a side view, with a middle portion protruding to the left in the figure. To explain in more detail, as shown in FIG. 3, the fixing member 15a includes a main body portion 15a51 forming a portion protruding to the left in the figure, and a pair of upper and lower flange portions 15a52 provided on the wall surface 12 side of the main body portion 15a51 so as to extend in the vertical direction along the wall surface 12. On the other hand, as shown in FIG. 3, the upper surface 15a1 of the main body portion 15a51 extends horizontally to the left in the figure (toward the supporting device 1), and the tip is formed by bending downward. Also, as shown in FIG. 3, a hook-shaped locking portion 15a2 for engaging with the rail member 15b is integrally formed in the middle portion of the main body portion 15a51 so as to protrude to the left in the figure (toward the supporting device 1). 3, a rail member mounting portion 15a3 having a substantially L-shape in a side view is formed so as to extend horizontally from the lower side of the locking portion 15a2, i.e., the bottom of the protruding portion of the main body portion 15a51, to the left in the figure (toward the supporting device 1). As shown in FIG. 3, a recessed portion 15a4 is formed at the base end of this rail member mounting portion 15a3.

[0023] Thus, the fixing members 15a of the first guide rail 15 configured as described above are fixed to the wall surface 12 with screws at predetermined intervals in the left-right direction shown in Fig. 1. Specifically, as shown in Fig. 3, the flange portion 15a52 on the upper end side of the fixing member 15a is fixed to the wall surface 12 with a screw B1, and the flange portion 15a52 on the lower end side is fixed to the wall surface 12 with a screw B2.

[0024] On the other hand, as shown in FIG. 3, the rail member 15b is composed of a rail main body 15b1 having a substantially rectangular shape in side view, and a guide groove frame 15b7 having an open upper surface and shaped like a letter C facing upward, which is formed integrally with the upper surface 15b2 of the rail main body 15b1 in the right direction in the figure. As shown in FIG. 3, the guide groove frame 15b7 is formed with a protruding portion 15b8 having a rectangular shape in side view, which protrudes integrally from the upper surface 15b7a to the right (toward the wall surface 12). Also, as shown in FIG. 3, a hook-shaped locking portion 15b4 for engaging with the fixing member 15a is integrally formed on the upper portion of the right side surface 15b1a (side surface on the wall surface 12 side) of the rail main body 15b1, protruding to the right (toward the wall surface 12). Furthermore, as shown in FIG. 3, a claw portion 15b5 is integrally formed on the lower portion of the right side surface 15b1a (side surface on the wall surface 12 side) of the rail main body 15b1, which protrudes downward.

[0025] Thus, as shown in FIG. 3, the rail member 15b of the first guide rail 15 as described above is fixed by screwing the protruding portion 15b8 of the guide groove frame 15b7 to the upper surface 15a1 of the main body portion 15a51 of the fixed member 15a. The locking portion 15b4 of the rail main body 15b1 is locked to the locking portion 15a2 of the fixed member 15a. The bottom surface 15b6 of the rail member 15b is placed on the rail member mounting portion 15a3 of the fixed member 15a, and the claw portion 15b5 of the rail member 15b fits into the recessed portion 15a4 of the fixed member 15a. Then, the rail member mounting portion 15a3 of the fixed member 15a and the bottom surface 15b6 of the rail member 15b shown in FIG. 3 are fixed by screwing the screws B3 at predetermined intervals in the left-right direction shown in FIG. 1. Therefore, in this manner, the rail member 15b is attached to the fixed member 15a fixed to the wall surface 12, thereby forming the first guide rail 15, as shown in FIGS.

[0026] <Explanation of the second guide rail> Next, we will explain the second guide rail 16. As shown in Figures 1 and 2, the second guide rail 16 is a member that extends in the left-right direction shown in Figure 1 so as to follow the lower end of the blackboard 10, is fixed to the wall surface 12, and has the second sliding part 6 attached thereto.

[0027] As shown in Figure 5, the second guide rail 16 is composed of a fixed member 16a fixed to the wall surface 12, a holding member 16b fixed to the fixed member 16a with screws and holding the rail member 16c, and the rail member 16c to which the second slide portion 6 is attached.

[0028] The fixing member 16a is a plate-like member that is L-shaped in side view as shown in Fig. 5. The holding member 16b is a plate-like member that is C-shaped downward in side view as shown in Fig. 5, and the upper surface is fixed to the fixing member 16a by a screw B4. Thus, as shown in Figs. 5 and 6, the fixing member 16a and the holding member 16b form a set and are arranged at a predetermined interval in the left-right direction shown in Fig. 1. As shown in Fig. 5, the vertical surface of the L-shaped fixing member 16a is fixed to the wall surface 12 by a screw B5.

[0029] On the other hand, the rail member 16c is formed in a downward C-shape when viewed from the side, as shown in Figures 5 and 6, and extends in the left-right direction as shown in Figure 1. Such rail member 16c is attached to the wall surface 12 by being held at a predetermined interval by holding member 16b, as shown in Figures 1, 5 and 6. In this way, the second guide rail 16 is formed.

[0030] <Description of the main body> Next, we will explain the main body 2. As shown in Figures 1 and 2, the main body 2 is a rectangular frame body formed by a pair of left and right vertical frames 3, 3 (upper vertical frames 3a, 3a, lower vertical frames 3c, 3c) and multiple horizontal frames (upper horizontal frame 4a, middle horizontal frame 4b, lower horizontal frame 4c, horizontal frames 4d, 4d for mounting the display device 11).

[0031] As shown in Figs. 1 and 2, a pair of left and right vertical frames 3, 3 are composed of upper vertical frames 3a, 3a and lower vertical frames 3c, 3c. The upper vertical frames 3a, 3a and the lower vertical frames 3c, 3c are each connected via inverted L-shaped members 3b, 3b as shown in Fig. 2 (note that Fig. 2 is a view of the support device 1 seen from the right side, but the upper vertical frame 3a on the left side and the lower vertical frame 3c on the left side are also connected in a similar manner). More specifically, as shown in Figs. 1 and 2, the middle horizontal frame 4b to which the lower end of the upper vertical frames 3a, 3a is fixed has both left and right ends shown in Fig. 1 fixed to the horizontal side 3b1 of the inverted L-shaped member 3b in side view as shown in Fig. 2. On the other hand, as shown in Fig. 2, the lower vertical frames 3c, 3c have their upper end rear faces fixed to the vertical side 3b2 of the inverted L-shaped member 3b.

[0032] With the above-mentioned configuration, as shown in Fig. 2, the lower vertical frame 3c is disposed closer to the viewer (left side in Fig. 2) than the upper vertical frame 3a. This allows the vertical frame 3 to not interfere with the chalk holder 10a of the blackboard 10. In other words, with this configuration, it is only necessary to dispose the lower vertical frame 3c away from the wall surface 12 so as not to interfere with the chalk holder 10a, and there is no need to displace the upper end of the upper vertical frame 3a away from the wall surface 12. This allows the vertical frame 3 to be placed as close to the blackboard 10 as possible, without leaving any unnecessary space between the blackboard 10 and the vertical frame 3.

[0033] The pair of left and right upper vertical frames 3a, 3a are rectangular columnar members that are long in the vertical direction as shown in Fig. 2, and as shown in Figs. 1 and 2, their upper ends are located slightly higher than the upper end of the blackboard 10, and their lower ends are located slightly higher than the lower end of the blackboard 10. The upper ends of these upper vertical frames 3a, 3a are provided with first sliding portions 5, 5 as shown in Fig. 1. Also, as shown in Figs. 1 and 2, the lower ends of the upper vertical frames 3a, 3a are fixed to the left and right ends of the intermediate horizontal frame 4b shown in Fig. 1, respectively.

[0034] As shown in Fig. 1, a pair of left and right handles 3a3, 3a3 are fixed with screws to the outer side surfaces of the pair of left and right upper vertical frames 3a, 3a. As shown in Fig. 1, the handles 3a3, 3a3 are formed long in the left and right direction so as not to be completely hidden by the display device 11 when viewed from the front. Note that the handles 3a3, 3a3 are not essential components of the present invention, and are therefore only shown in Fig. 1.

[0035] On the other hand, the pair of lower vertical frames 3c, 3c are rectangular column-shaped members elongated in the vertical direction as shown in FIG. 2, and as shown in FIGS. 1 and 2, the upper end is located slightly higher than the lower end of the blackboard 10, and the lower end is located slightly higher than the floor surface 13. As shown in FIGS. 1 and 2, the lower end of each of the lower vertical frames 3c, 3c is provided with a wheel 7. Also, as shown in FIGS. 1 and 2, the vertical intermediate portion of each of the lower vertical frames 3c, 3c is provided with a second slide portion 6. Furthermore, as shown in FIGS. 1 and 2, a folding table 3c1 is provided on the upper side of the lower vertical frame 3c. As shown in FIG. 2, the folding table 3c1 is mainly composed of a shelf-side metal fitting 3c21 fixed to the back side of the table board, a wall-side metal fitting 3c22 fixed to the lower vertical frame 3c, and a stay metal fitting 3c23 that holds the shelf-side metal fitting 3c21 and the wall-side metal fitting 3c22 in a 90-degree open state. Incidentally, since a folding table having such a configuration is conventionally known, a detailed description thereof will be omitted.

[0036] Thus, the upper horizontal frame 4a, the middle horizontal frame 4b, the lower horizontal frame 4c, and the horizontal frame 4d for mounting the display device 11 to the support device 1 are attached to the vertical frame 3, 3 consisting of the upper vertical frames 3a, 3a and the lower vertical frames 3c, 3c as described above.

[0037] As shown in Figs. 1 and 2, the upper horizontal frame 4a is fixed to the upper side of a pair of upper vertical frames 3a, 3a. As shown in Figs. 1 and 2, a pair of adjustment bolts 4a1, 4a1 are provided on both the left and right ends of the upper horizontal frame 4a. As shown in Fig. 2, the adjustment bolts 4a1, 4a1 are fixed to an L-shaped mounting member 4a2 fixed on the upper horizontal frame 4a by bolt and nut fastening. As shown in Fig. 2, the adjustment bolts 4a1, 4a1 have a base portion 4a3 covered with a rubber cover at their tips (left side of Fig. 2), and the base portion 4a3 can be abutted against the back surface of the display device 11 by rotating the adjustment bolts 4a1, 4a1 relative to the nuts. This makes it possible to prevent the display device 11 from rattling.

[0038] The intermediate horizontal frame 4b is fixed to the lower end portions of the pair of upper vertical frames 3a, 3a on the left and right sides as shown in Figures 1 and 2. Also, as shown in Figures 1 and 2, the intermediate horizontal frame 4b is provided at both left and right ends with a pair of adjustment bolts 4b1, 4b1 having the same configuration as the adjustment bolt 4a1 of the upper horizontal frame 4a.

[0039] As shown in FIG. 1, the lower horizontal frame 4c is fixed to the lower sides of the pair of left and right lower vertical frames 3c, 3c.

[0040] A pair of upper and lower horizontal frames 4d, 4d for mounting the display device 11 to the support device 1 are positioned between the upper horizontal frame 4a and the middle horizontal frame 4b, as shown in Figure 1, and are attached to a pair of left and right upper vertical frames 3a, 3a.

[0041] The horizontal frames 4d, 4d are fixed to the rear surface of the display device 11 before the display device 11 is installed on the stand device 1. In other words, the horizontal frames 4d, 4d are attached in order to show the state in which the display device 11 is installed on the stand device 1, but when the display device 11 is not installed on the stand device 1, the horizontal frames 4d, 4d are not attached to the upper vertical frames 3a, 3a.

[0042] Thus, as described above, the main body 2 is formed into a rectangular frame by attaching multiple horizontal frames (upper horizontal frame 4a, middle horizontal frame 4b, lower horizontal frame 4c, horizontal frame 4d for mounting the display device 11) to multiple pairs of left and right vertical frames 3, 3 (upper vertical frames 3a, 3a and lower vertical frames 3c, 3c).

[0043] <Explanation of the first slide part> Next, a description will be given of the first sliding portion 5. As shown in Fig. 1 and Fig. 2, the first sliding portions 5, 5 are attached to the upper ends of the pair of left and right upper vertical frames 3a, 3a, respectively, and are attached to the first guide rail 15, and slide in the left-right direction shown in Fig. 1 along the first guide rail 15.

[0044] As shown in Figures 3 and 4, the pair of first slide parts 5 is composed of a slider 5a and an arm 5g that supports the slider 5a. Furthermore, as shown in Figures 3 and 4, the slider 5a is mainly composed of a slider body 5b, and a roller group 5c, a vertical roller 5d, and a horizontal roller 5e attached to the slider body 5b.

[0045] As shown in Fig. 3, the slider body 5b is formed of a horizontal upper surface 5b1, a vertical portion 5b3 on the right side of the figure, and a vertical portion 5b4 on the left side of the figure, and has a U-shape facing downward in side view. More specifically, as shown in Fig. 4, the vertical portion 5b3, which is rectangular in side view, extends downward from the wall surface 12 side end (right end in the figure) of the upper surface 5b1 formed in a rectangular shape long in the left-right direction of the figure, and is provided with a roller group 5c consisting of multiple rollers on the lower side. As shown in Figs. 3 and 4, the roller group 5c is composed of horizontal rollers provided at both the left and right ends of the vertical portion 5b3 shown in Fig. 4 and rotating in the horizontal direction, and vertical rollers arranged between these rollers and rotating in the vertical direction.

[0046] On the other hand, as shown in Fig. 3, a vertical portion 5b4 having a rectangular shape in a side view extends downward from the end portion (left end portion in the figure) of the upper surface 5b1 on the side of the supporting device 1, and further, a protruding portion 5b5 protrudes integrally from the lower end portion of the vertical portion 5b4 toward the supporting device 1 side (left side in the figure). As shown in Figs. 3 and 4, and particularly as shown in Fig. 4, a pair of left and right vertical rollers 5d are provided on the vertical portion 5b4, and a pair of left and right horizontal rollers 5e are provided on the protruding portion 5b5.

[0047] Thus, the roller group 5c, vertical roller 5d, and horizontal roller 5e are mounted so as to be able to roll on the first guide rail 15, as shown in Figs. 3 and 4. More specifically, as shown in Fig. 3, the roller group 5c is mounted so as to be able to roll on the guide groove frame 15b7 of the first guide rail 15. Also, as shown in Fig. 3, the vertical roller 5d is in rollable contact with the upper surface 15b2 of the rail main body 15b1 of the first guide rail 15. Furthermore, as shown in Fig. 3, the horizontal roller 5e is in rollable contact with the side surface 15b3 of the rail main body 15b1 of the first guide rail 15.

[0048] In addition, if there is play in the roller group 5c in the guide groove frame 15b7, the first slide portion 5 will rattle, and the rattle will be transmitted to the display device 11 through the upper vertical frame 3a, causing the display device 11 to malfunction. Therefore, the shaft hole (not shown) provided in the protruding portion 5b5 for inserting the shaft portion 5e1 of the horizontal roller 5e shown in FIG. 3 is formed as a long hole that is long in the left-right direction of FIG. 3, and the mounting position of the horizontal roller 5e can be adjusted in the left-right direction of FIG. 3. This configuration can reduce the play of the roller group 5c in the guide groove frame 15b7. That is, in order to press the roller group 5c against the inner wall on the support device 1 side (left side of FIG. 3) in the guide groove frame 15b7 and maintain this state, the shaft portion 5e1 of the horizontal roller 5e can be mounted at a position to the right of the shaft hole (long hole) provided in the protruding portion 5b5. In this way, the amount of play of the roller group 5c in the guide groove frame 15b7 can be reduced, and the display device 11 can be prevented from malfunctioning.

[0049] Incidentally, the slider 5a as described above is attached to the upper end of the upper vertical frame 3a via an arm 5g, as shown in Fig. 3. The arm 5g is a rectangular prism-shaped member extending in the front-rear direction (extending in the left-right direction in Fig. 3), and as shown in Figs. 3 and 4, its base end side (the left end side in Fig. 3) is fixed to the upper end of the upper vertical frame 3a, and the slider 5a is attached to its tip side (the right end side in Fig. 3).

[0050] More specifically, as shown in Fig. 3, the base end side of the arm 5g (the left end side shown in Fig. 3) is fixed to the upper vertical frame 3a by a plurality of T-lock coupling parts B82 (two are shown in Fig. 3) inserted into T-slots (not shown) formed on the side of the upper vertical frame 3a, and a tapered bolt B81 (two are shown in Fig. 3) that fastens and fixes the plurality of T-lock coupling parts B82 at a predetermined position of the upper vertical frame 3a. Furthermore, a plate member 5g1 is placed on top of the T-lock coupling parts B82 and is fixed with a plurality of screws B6 (three in the figure). Although this plate member 5g1 is not necessarily required, the plate member 5g1 is provided so that the fixed position of the upper vertical frame 3a can be maintained even if an accident occurs, such as the plurality of T-lock coupling parts B82 or the tapered bolt B81 falling off.

[0051] On the other hand, as shown in Figs. 3 and 4, the slider 5a is attached to the tip side (the right end side shown in Fig. 3) of the arm 5g via an attachment member 5g2. As shown in Fig. 4, the attachment member 5g2 is a pair of members provided on the left and right sides of the arm 5g, and as shown in Figs. 3 and 4, it is composed of a vertical surface 5g21 that is abutted against the arm 5g and a horizontal surface 5g22 that is abutted against the slider 5a. To explain in more detail, as shown in Fig. 3, the vertical surface 5g21 is formed in a rectangular shape that is long in the left-right direction, and is fixed to the arm 5g by a plurality of screws B8 (six are illustrated in Fig. 3, six on each side). On the other hand, as shown in Fig. 3, the horizontal surface 5g22 is formed to the same length as the vertical surface 5g21, and is fixed to the upper surface 5b1 of the slider 5a by a plurality of screws B7 (two are illustrated in Fig. 3, two on each side). As shown in FIG. 4, the shape of this horizontal surface 5g22 consists of a rectangular portion fixed to the upper surface 5b1 of the slider 5a with a plurality of screws B7, and a trapezoidal portion extending from the end of the rectangular portion on the support device 1 side (the lower side in the figure) and gradually narrowing in width.

[0052] Thus, in this manner, the slider 5a is attached to the upper end of the upper vertical frame 3a via the arm 5g.

[0053] Incidentally, as shown in FIG. 3, the mounting position of the arm 5g on the mounting member 5g2 can be shifted in the left-right direction in the figure. Therefore, as shown in FIG. 2, the first slide section 5 can adjust the distance 5L from the wall surface 12 to the support device 1. This makes it possible to easily change the position of the upper vertical frame 3a relative to the blackboard 10 or the wall surface 12, and therefore makes it possible to arbitrarily change the position of the vertical frame 3, i.e., the main body 2. Therefore, the main body 2 can be simply and easily installed on the blackboard 10 or the wall surface 12 of various thicknesses. Note that even if the arm 5g is shifted in the direction away from the wall surface 12 (left side in FIG. 3) and attached to the mounting member 5g2, as shown in FIG. 3, the vertical surface 5g21 and the horizontal surface 5g22 of the mounting member 5g2 are formed in a rectangular shape that is long in the left-right direction in the figure, so that the display device 11 can be supported with sufficient strength.

[0054] In addition, the shaft hole provided in the horizontal side 3b1 of the inverted L-shaped member 3b shown in Fig. 2 is a long hole that is long in the left-right direction in the figure, and the attachment position of the intermediate horizontal frame 4b to the horizontal side 3b1 can be adjusted in the left-right direction in Fig. 2. Therefore, when adjusting the distance 5L, it is possible to change only the position of the upper vertical frame 3a in the left-right direction in Fig. 2 by adjusting the attachment position of the intermediate horizontal frame 4b to the horizontal side 3b1 without changing the position of the lower vertical frame 3c.

[0055] <Explanation of the second slide part> Next, a description will be given of the second sliding portion 6. As shown in Figures 1 and 2, the second sliding portions 6, 6 are attached to the vertical middle portions of the pair of left and right lower vertical frames 3c, 3c, respectively, and are attached to the second guide rail 16 so as to slide left and right along the second guide rail 16.

[0056] As shown in Fig. 5, the pair of second slide parts 6 is composed of a slider 6a and an arm 6g that supports the slider 6a. Furthermore, as shown in Fig. 5, the slider 6a is mainly composed of a slider body 6b and a roller group 6c attached to the slider body 6b.

[0057] As shown in FIG. 5, the slider body 6b is a plate-like member that is fixed to the tip side surface (the right end surface in the figure) of the arm 6g with a screw B9 and is sector-shaped when viewed from the front (see FIG. 1).

[0058] As shown in Figures 5 and 6, the slider body 6b has a roller group 6c consisting of multiple rollers on the upper side. Note that, as shown in Figures 5 and 6, the roller group 6c is composed of horizontal rollers that are provided on both the left and right ends of the upper side of the slider body 6b as shown in Figure 6 and rotate in the horizontal direction, and vertical rollers that are disposed between these rollers and rotate in the vertical direction.

[0059] The roller group 6c is mounted so as to be capable of rolling within a rail member 16c of the second guide rail 16, as shown in FIGS.

[0060] Incidentally, the slider 6a as described above is attached to the lower vertical frame 3c, 3c at a predetermined position in the up-down direction (slightly above the middle part in the figure) via an arm 6g, as shown in FIG. 2. The arm 6g is composed of a first arm 6g1 attached to the lower vertical frame 3c, and a second arm 6g2 attached to the first arm 6g1 in a nested manner, as shown in FIGS. 5 and 6. To explain more specifically, first, as shown in FIG. 5, a U-shaped metal fitting 6g3 is fixed to the base end side (left end side in the figure) of the first arm 6g1 by a plurality of screws B10 (four screws are illustrated in the figure). Then, as shown in FIG. 5, the base end side (left end side in the figure) of the first arm 6g1 is abutted against the side surface of the lower vertical frame 3c at a predetermined position in the up-down direction (slightly above the middle part in the figure) as shown in FIG. 2, and is fixed to the lower vertical frame 3c by screws B11 as shown in FIG. 5. On the other hand, as shown in Fig. 5, the tip side (right end side in the figure) of the first arm 6g1 has the second arm 6g2 nested within it and is fixed with a plurality of screws B12 (four are illustrated in the figure). Then, as shown in Fig. 5, the slider body 6b is fixed with screws B9 to the tip side (right end side in the figure) of the second arm 6g2. Thus, the slider 6a is attached to a predetermined position in the up-down direction of the lower vertical frame 3c (slightly above the middle part in the figure) via the arm 6g (first arm 6g1, second arm 6g2) as shown in Fig. 2.

[0061] As shown in Figures 5 and 6, the first arm 6g1 accommodates the second arm 6g2 in a nested manner, and the length of the entire arm 6g can be adjusted by changing the accommodation length. Therefore, as shown in Figure 2, the second slide section 6 can adjust the distance 6L from the wall surface 12 to the support device 1. This makes it possible to easily change the position of the lower vertical frame 3c relative to the blackboard 10 or the wall surface 12, and therefore makes it possible to arbitrarily change the position of the vertical frame 3, i.e., the main body section 2. Therefore, the main body section 2 can be easily installed on blackboards 10 and wall surfaces 12 of various thicknesses.

[0062] <Wheel Description> Next, the wheels 7 will be described. As shown in Fig. 1, the wheels 7 are attached to the lower side of the lower vertical frame 3c constituting the main body 2 so as to be in contact with the floor surface, and run left and right on the floor surface while supporting the support device 1.

[0063] As shown in Fig. 1, in this embodiment, shock-absorbing spring casters are used as the wheels 7. Also, as shown in Fig. 2, in this embodiment, a podium 14 is installed under a blackboard 10. The wheels 7 run on a passage 14a, which is a hollow space provided in the podium 14.

[0064] <How to install the support device> Next, a method for installing the supporting device 1 configured as above will be described.

[0065] First, as shown in Fig. 1, a first guide rail 15 is fixed to a wall surface 12 so as to fit along the upper end of the blackboard 10. Also, a second guide rail 16 is fixed to the wall surface 12 so as to fit along the lower end of the blackboard 10. Furthermore, as shown in Fig. 3, the slider 5a of the first sliding portion 5 is attached to the first guide rail 15, and as shown in Fig. 5, the slider 6a of the second sliding portion 6 is attached to the second guide rail 16.

[0066] Meanwhile, as shown in Fig. 1, to assemble the main body 2, multiple horizontal frames (upper horizontal frame 4a, middle horizontal frame 4b, lower horizontal frame 4c) are fixed to a pair of left and right vertical frames 3 (upper vertical frame 3a, lower vertical frame 3c) to assemble a rectangular frame body. At this time, wheels 7 are attached to the underside of the lower vertical frame 3c. Furthermore, as shown in Fig. 1, an arm 5g of the first slide section 5 is attached to the upper end of the upper vertical frame 3a, and as shown in Fig. 2, an arm 6g of the second slide section 6 is attached to a predetermined position of the lower vertical frame 3c (slightly above the middle part in the figure).

[0067] Meanwhile, the horizontal frame 4d is fixed in advance to the back surface of the display device 11. That is, before the display device 11 is placed on the support device 1, the horizontal frames 4d, 4d are fitted with a plurality of circular screw holes 4d5 (see FIG. 1) (three in FIG. 1) provided at each of the left and right ends thereof and a screw hole (not shown) provided in advance on the back surface of the display device 11, and the display device 11 is fixed in place with screws.

[0068] Next, the assembled main body 2 is stood up and, with a predetermined distance away from the wall surface 12, the slider 5a attached to the first guide rail 15 is fixed to the arm 5g with screws (see Figure 3), and the slider 6a attached to the second guide rail 16 is fixed to the arm 6g with screws (see Figure 5).

[0069] Then, the display device 11 with the horizontal frames 4d, 4d attached to the top and bottom of the back surface is lifted above the support device 1 as shown in FIG. 1, and the horizontal frames 4d, 4d are attached to the upper vertical frame 3a, thereby installing the display device 11 on the support device 1.

[0070] In this manner, the supporting device 1 can be installed.

[0071] In this embodiment, a pulley 8 shown in Fig. 7(a) can be used to lift the display device 11 to which the horizontal frames 4d, 4d are attached above the support device 1. As shown in Figs. 1 and 2, one pulley 8 is attached to each of the outer side surfaces of the upper sides of the pair of upper vertical frames 3a, 3a on the left and right.

[0072] As shown in FIG. 7(a), one pulley 8 is fixed to the outer side surface of the upper vertical frame 3a via a metal plate 8a with a plurality of screws B13 (two in the figure). When installing the display device 11 on the support device 1, a wire 8c is passed through the grooves 8b (see FIG. 7(a)) of a pair of pulleys 8 attached to the pair of upper vertical frames 3a, 3a, as shown in FIG. 7(b). Then, when one end of the wire 8c is attached to the display device 11 before installation (for example, the display device 11A in a face-down state shown in FIG. 7(b)) and the other end is pulled in the direction of the arrow 8d, the display device 11 before installation is pulled upward and becomes an upright state 11B. In this way, even a large display device with a large weight can be easily lifted to a predetermined position using the principle of a pulley.

[0073] In this embodiment, the pulleys 8 are attached to the outer side surfaces of the upper vertical frames 3a, 3a as shown in Figs. 1 and 2, but they may be attached to the inner side surfaces of the upper vertical frames 3a, 3a.

[0074] In addition, in this embodiment, the horizontal frames 4d, 4d attached to the display device 11 lifted to a predetermined position by the pulley 8 can be easily attached using the engaging members 4d2 provided on the back surfaces of both the left and right ends of the horizontal frames 4d, 4d, as shown in Figure 8.

[0075] More specifically, as shown in Fig. 8, a groove 3a4 is provided in the longitudinal direction on the outer side surface 3a1 of the upper vertical frame 3a (Fig. 8 illustrates the upper vertical frame 3a on the right side shown in Fig. 1), and a long and narrow plate-like member 3a2 is fitted into a predetermined position of this groove 3a4 (a position corresponding to the height at which the display device 11 is to be attached to the support device 1) and fixed with a screw (not shown). As shown in Fig. 8, a bolt 3a2a is provided in the vertical center of this plate-like member 3a2 with its tip protruding outward. A total of four plate-like members 3a2 having such a configuration are provided, two on each of the outer side surfaces of the pair of left and right upper vertical frames 3a, 3a.

[0076] On the other hand, as shown in Fig. 8, a fitting member 4d2, which is an L-shaped member, is provided on the back surface 4d1 of the horizontal frame 4d. A surface 4d2a of the fitting member 4d2 that is along the back surface 4d1 of the horizontal frame 4d is fixed to the horizontal frame 4d with a plurality of screws (not shown). On the other hand, a surface 4d2b of the fitting member 4d2 that is along the upper vertical frame 3a is provided with a U-shaped fitting groove 4d4 that can be fitted into a bolt 3a2a provided on the upper vertical frame 3a. A total of four fitting members 4d2 having such a configuration are provided, one on each of the back surfaces of the pair of upper and lower horizontal frames 4d, 4d (see Fig. 2).

[0077] Thus, when attaching the horizontal frames 4d, 4d attached to the display device 11 (the display device 11 in the upright state 11B shown in FIG. 7(b)) that has been lifted to a predetermined position by the pulley 8 with the above-mentioned configuration to the upper vertical frame 3a, first, the fitting groove 4d4 of the fitting member 4d2 is hooked onto the bolt 3a2a. Furthermore, a nut (not shown) is fastened to the bolt 3a2a. This allows the display device 11 to be simply, easily, and firmly fixed to the upper vertical frame 3a.

[0078] Therefore, according to the present embodiment described above, even if the weight of the display device 11 is large, it can be supported safely. That is, in the past, the load of the weight of the display device 11 was only applied to the wall surface 12, which may have been damaged, but according to the present embodiment, the wheels 7 are in contact with the floor surface and bear at least a part of the load, so that even if the weight of the display device 11 is large, it can be supported safely. Moreover, since the wheels 7 do not require guide rails, there is no need to provide guide rails on the floor surface, making installation easy.

[0079] Therefore, according to this embodiment, it is possible to provide a supporting device that can safely support even a heavy display device.

[0080] <Description of Modifications> The support device 1 shown in this embodiment is merely an example, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims. For example, in this embodiment, an example is shown in which the support device 1 is installed on the blackboard 10, but the blackboard 10 may be an electronic blackboard, a whiteboard, or the like.
